I've spent the last hour looking at plumbing parts (fixtures? idk) trying to find a "female-female" 20mm aerator or adapter for the tiny dishwasher I just bought and haven't been able to use, and I KNOW it exists bc I saw one in a youtube video, but it either doesn't exist in real life or I'm googling the wrong thing

ANYway, gender essentialist plumbing terms aside, the only possible reason for this not existing is clearly that it's the lesbian adapter, so it's never manufactured
